<p class="MsoNormal" style="margin-bottom:12.0pt">Hi,<br>
<br>
I am using the proxy server implementation which sends a PAUSE command when no clients are connected for a registered URL. In our setup we have to handle live camera images and I am not sure if a PAUSE command will have effect on such cameras. Therefore, I
changed the PAUSE command into a TEARDOWN command. This is working, however, the first keep-alive-message in the form of sending an OPTIONS command will fail after sending a TEARDOWN (because of a "stream not found") and the ProxyServerMediaSubSession object
is deleted and created again. After creation the keep-alive message succeeds again.<br>
<br>
Is there another way to restore the connection after a TEARDOWN command?<o:p></o:p></p>
